Maintenance - Lexicon LDD-1 User Manual

The LDD-1 chassis is barely four inches deep to allow it to be positioned adjacent to an AC-3-capable
player's RF output. This minimizes the required RF-signal cable length to reduce any RF interference.
As the unit uses automated switching, and draws very little power, you can literally set it and forget it.
To set up the LDD-1:
• Connect a 75 coaxial cable between the LDD-1 rear panel RF (AC-3) input and the laser disc
player's RF/AC-3 output. Keep this cable as short as possible to minimize RF interference.
• Connect a 75 coaxial (or optical) cable between the LDD-1 S/PDIF input and the laser disc
player's digital output.
• Connect a 75 coaxial cable betwen the LDD-1 S/PDIF output and the DC-1 COAX 1 digital input.
• Recommended: Connect a 5-pin DIN cord (not supplied) between the LDD-1 PWR CTL input and
the DC-1 PWR CTL output. This allows the LDD-1 to power on and off with the DC-1. If this
connection is not made, the LDD-1 will turn on whenever its AC adapter is supplied power.
• Optional: Connect any additional components which allow remote turn on (such as Lexicon's NT
Series of power amplifiers) to the LDD-1 rear panel PWR CTL (LOOP THRU) connector.
• Connect the AC adapter provided to the POWER jack.
Once the LDD-1 is properly connected, set the front panel INPUT SELECT switch for the appropriate
type of NON-AC-3/RF digital output you are using on your laser disc player. (Most laser disc players
have only one.) Set the LD OPTIMIZATION switch according to the chart provided on page 2. Once you
have completed the connections and setting of the front panel switches, all functions are performed
automatically. LEDs on the front panel are provided to identify the operational state.
The LDD-1 requires no maintenance. However, it is good electrical practice to clean all connectors once
a year. Clean the exterior surfaces of the unit with a soft, lint-free cloth, dampened with warm water.
